Ethylcellulose melting point

Ethylcellulose yog ib qho thermoplastic polymer, thiab nws softens ntau dua li melts ntawm qhov kub siab. Nws tsis muaj qhov sib txawv melting point zoo li qee cov ntaub ntawv crystalline. Hloov chaw, nws dhau los ua cov txheej txheem softening nrog nce kub.

Lub softening los yog iav hloov kub (Tg) ntawm ethylcellulose feem ntau ntog nyob rau hauv ib tug ntau yam es tsis yog ib tug tshwj xeeb point. Qhov ntsuas kub no nyob ntawm qhov xwm txheej xws li qib ntawm ethoxy hloov pauv, qhov hnyav molecular, thiab kev tsim tshwj xeeb.

Feem ntau, cov iav hloov pauv kub ntawm ethylcellulose nyob rau hauv thaj tsam ntawm 135 txog 155 degrees Celsius (275 txog 311 degrees Fahrenheit). Qhov no qhia tau hais tias qhov kub thiab txias ntawm ethylcellulose yuav hloov tau yooj yim dua thiab tsis nruj, hloov ntawm lub iav mus rau lub xeev rubbery.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus cwj pwm softening ntawm ethylcellulose tuaj yeem sib txawv raws li nws daim ntawv thov thiab muaj lwm cov khoom xyaw hauv cov qauv. Rau cov ntaub ntawv tshwj xeeb txog cov khoom lag luam ethylcellulose koj siv, nws raug nquahu kom xa mus rau cov ntaub ntawv kev qhia los ntawm Ethyl cellulose chaw tsim tshuaj paus.
